[Boost-users] shared memory between 32b and 64b

Looked promising, but not quite good enough. I dedined: typedef offset_ptr<class T, std::ptrdiff_t, unsigned long long>my_offset_ptr; typedef basic_managed_shared_memory <char ,rbtree_best_fit<mutex_family, my_offset_ptr> ,iset_index> compat32_shared_memory; in the win64 process I do compat32_shared_memory segment(create_only, SEGMENT_NAME, SEGMENT_SIZE); comm *command = segment.construct<comm>("CommandBlock")(); in the win32 process in do compat32_shared_memory segment(open_only, SEGMENT_NAME); std::pair<comm *,size_t>com = segment.find<comm>("CommandBlock"); the "find" never returns. The code works fine if both processes are win32 or both are win64 Am I on the right track?
